Birds hitting windows

[bluejay55]

Can anyone help.  In the morning the sun hits my very large back window.  Every once in awhile a bird will fly into it.  So far there have not been any casualties.  The problem is, even if I stick something on the inside of the window the sun is still reflecting off the window so the birds cannot see it.  Does anyone have any ideas?

These are ultraviolet decals. They don't inhibit views but they act as a stop sign for birds by making the window visible.

Thank you so much Sahria.  I will look in to it.

What I am trying now seems to work better than other methods tried.  I string feathers evenly along fishing line and attach the line vertically to the windows, large windows obviously use more lines of feathers than others.   I know the birds do definitely notice them and the hummingbirds actually hover in front of the red feathers, ignoring other colours.
